The Influence of Age and Gender on Tongue Pressure and Swallowing Tongue Pressure

The main topic of the research is to investigate the tongue's strength when swallowing. There has been much foreign literature on tongue strength. Iowa Oral Performance Instrument also has norms for reference, but the data are all taken from non-Asian people such as Caucasians. In this case, the credibility of the norms are decreased in domestic, and we also lack norm data of tongue strength when swallowing. Through the research, we can establish normative data belonging to the domestics, provide usable data for domestic researchers and clinical staff, and explore whether there are differences in age and gender in data between Taiwanese and foreigners.
